1 INTRODUCTION
The Harmonics & Flicker Generator 02 (HFG02) has been designed by York EMC
Services for the purpose of providing an easy and reliable way to externally check
the performance of measurement systems used for testing against the EN/IEC
61000-3-2 harmonics and interharmonics and EN/IEC 61000-3-3 flicker standards.
The HFG02 allows the user to periodically verify their test equipment and its
operation together, helping to ensure compliance with standards and laboratory
quality procedures.
The HFG02 provides a series of harmonic and flicker disturbances of a nominal
but stable level. The HFG02 may therefore be used to verify the stability of a
measurement system. Additionally, due to its own stability it may be used as a
transfer standard from a calibrated system, or be used as a repeatable source of
interference for diagnostic and/or development design work.

2 DESCRIPTION
The HFG02 simulates equipment under test (EUT), generating known, repeatable
levels of harmonic and flicker disturbance in one of ten modes of operation. These
modes are divided into flicker, harmonics and EUT profiles.
The flicker test modes generate a fixed level of mains disturbance at a rate of 1 Hz
and 8.33/8.6 Hz, depending on the frequency of the Test Supply under test. These
modes support verification of the test systems used for EUT flicker disturbance
measurements as described in the EN/IEC 61000-3-3 test standards.
The harmonics test modes are designed to produce a variety of harmonic and/or
interharmonic-rich current waveforms. These current waveforms support
verification of the test systems used for mains-powered equipment load current
testing as described in the EN/IEC 61000-3-2 test standards.
A selection of EUT modes is also provided. These modes generate disturbances
which simulate certain types of real-world EUT not covered by the generalised
harmonics and flicker modes.
The HFG02 can be used with test systems operating at both 110 Vac and 230 Vac
(nominal) supply voltages, and with either 50 Hz or 60 Hz supply frequencies. The
HFG02 constantly monitors the Test Supply under test and adjusts itself
automatically, indicating the detected voltage and frequency to the operator.
Connection to the test system is by a captive lead pre-fitted with a CEE 7/7
European style plug that fits directly with power outlet used by a wide range of
harmonics and flicker equipment.
The HFG02 itself is powered by a wide-input range AC/DC power supply unit that
is powered separately from the Test Supply under test. This ensures that the
disturbance signals generated by the HFG02 are not affected by the need to derive
the HFG02’s own supply needs from the Test Supply under test.
For ease of access all connections, user controls, and indicators are located on
the front panel of the HFG02. The HFG02 is supplied with the external power unit
with mains cable, manufacturer’s test certificate, and a CDROM containing digital
copies of the manual, test certificate, and files of the tabulated certificate data.

5 OPERATION
5.1 Controls and indicators
Identifier Description
Start Test Pressing this switch enables the test mode, and applies the
chosen load profile to the measurement system, as appropriate
for the test supply detected.
Pressing this switch again whilst the test is running disables the
test mode.
Test enabled indicator Indicates that the test mode is running.
Test Mode selector This switch selects one of ten load profile test modes available to
be used. Changing this setting whilst a test is running will
automatically disable the current test mode.
Alarm indicator This indicator flashes if the temperature within the enclosure
exceeds the preset limit. In this state the test mode will be
disabled and the HFG02 will wait until the temperature has
dropped sufficiently before the test can be resumed.
A steady indicator warns of a system failure, which will need to
be cleared by fully restarting the HFG02 (refer to Section 4.7).
Test Supply indicators These indicators display the frequency and RMS voltage of the
Test Supply. Section 5.5. gives details of the ranges indicated.

5.5 Test Supply Indicators
The HFG02 monitors the input from the Test Supply under test and displays the
voltage and frequency measurements on the front panel indicators as shown in
Table 2.
Test Supply monitoring is continuous and automatic, and does not require a test
mode to be enabled. Tests are automatically disabled if the Test Supply voltage or
frequency are outside their permitted ranges.

5.6 Performing a test.
The HFG02 acts as the equipment under test in the harmonics and flicker test
system, and should be connected to the single-phase test power supply as per the
typical test setup used (Figure 5 for example).
Figure 5: Example of a typical test setup
Connect the HFG02 power supply and turn the HFG02 on by pressing the
power switch . The power supply indicator should be illuminated green to
indicate the HFG02 is operating correctly.
The Test Supply Input cable can be plugged into the Test Supply power output
socket. Note that if the Test Supply does not provide a safety earth connection as
one of the conductors (e.g. 2-pin Live and Neutral only) then the Chassis Earth
wiring stud on the front of the HFG02 must be connected to a suitable earth first
(not shown). A suitable earth point may be provided elsewhere on the Harmonics
and Flicker test system.
Configure the Harmonics and Flicker Test System to measure harmonic or flicker
disturbance as per the system instructions, with the Test Supply configured to
provide the required voltage and frequency.
Once the Test Supply has been safely connected, the Harmonics and Flicker Test
Supply can be enabled. The HFG02 Test Supply indicators should show
confirmation of the selected Test Supply output voltage and frequency.
Select the required test load operation using the Test Mode switch .

HFG02 Operation Manual
York EMC Services Page 15 of 25 Doc. No. Y0321/DOC/024 Rev. 3
The chosen test load operation can be enabled before or after the Harmonics and
Flicker Test System has started the test routine. When ready to enable the load
operation, press the Start Test switch . The Test Enable display should
indicate that the test is running.
Pressing the Start Test switch again will disable the running test. Changing the
Test Mode selection switch will also disable the running test. The new selected
test will need to be started by pressing the Start Test switch again.
Note:
If the HFG02 test has been running for more than 2 hours continuously it is
recommended that it is allowed to cool down before power is finally removed, to
reduce any latent heat build-up. To do this, leave the HFG02 turned on but with no
running test for approximately 10 to 15 minutes before fully powering down.
5.7 Troubleshooting a test
The HFG02 monitors the Test Supply input from the Harmonics and Flicker Test
System and reports the measured voltage and frequency on the front panel display
(see Table 2). If an invalid voltage or frequency is detected, the test load operation
will be disabled (Test Enable display will be OFF).
The test load operation will also be disabled if the HFG02 detects too many
dropped voltage cycles or interruptions from the Test Supply.
If the HFG02 load exceeds its recommended operating temperature, the test load
operation will be disabled (Test Enable display will be OFF) and the Alarm
indicator will flash at a steady rate. Once the temperature has returned to
normal the Alarm indicator will turn off and the test can be resumed.
If the HFG02 detects a system error, the Alarm indicator will fully turn on without
flashing. The system error will need to be cleared by removing all power from the
HFG02 before fully restarting. If fully restarting the device fails to clear the error,
the HFG02 may require servicing.
The Alarm indicator will also fully turn on if a serious error has been detected with
the Test Supply voltage e.g. surge or transient overvoltages sufficient to cause
damage to the HFG02 itself. This error can be cleared by disconnecting the Test
Supply and restarting the HFG02.
A flowchart for troubleshooting if the test cannot be enabled is shown in Figure 6.
In the case of other problems, please contact your supplier for advice.
